Join Jon Bott for an in-depth discussion in this video Traits, part of RxSwift: Design Patterns for iOS Developers.
- [Instructor] The next type to talk about are traits,…which are just specialized observables.…I don't think it's worth your time…to watch me type all of this out…because you will be using these in a template form…over and over again,…and so I've provided a file inside of your exercise files.…Under the starter project,…there's a file called TraitsRx.swift.…Let's go ahead and bring this over to our project…and put it in the simple examples folder…and let's go ahead…and take a look at what this TraitsRx file looks like.…
It's just a singleton,…and we have a DisposeBag,…but the pieces I want you to focus on are lines 11,…lines 35, and line 60.…Each of these has an example for the different type…of traits you would be using.…Traits are really similar to observables…in how we create them,…the set of observables…and type out create.…We'll say single type dot create.…The only other difference in here…is that instead of posting an event like on next…or on error,…we're actually just using the single…as if it's a closure…and we're handing it either success or error…
